Product details

Overview

64-2143PBF from Infineon Technologies is an N-channel enhancement-mode power MOSFET in D2PAK (TO-263) package, rated for 100 V V_DS, 17 A continuous drain current at T_C = 25°C, and R_DS(on) ≤ 45 mΩ at V_GS = 10 V. It serves as a main switching device in DC-DC converters and motor drive half-bridges.

For engineers reviewing the 64-2143PBF datasheet, 64-2143PBF pinout, 64-2143PBF application, or 64-2143PBF equivalent, key selection criteria include its 100 V blocking capability, low on-resistance under standard gate drive, thermal performance in surface-mount power stages, and suitability for synchronous rectification in buck converters.

Technical Context

This MOSFET uses Infineon's OptiMOS™ 3 technology, optimized for high-efficiency switching in 12–48 V input systems. Its gate threshold voltage (V_GS(th)) ranges from 2.0 V to 4.0 V, enabling compatibility with 3.3 V and 5 V logic-level gate drivers.

The device features a fully avalanche-rated structure (E_AS = 120 mJ at T_J = 25°C), integrated body diode with soft recovery (t_rr = 55 ns), and specified safe operating area (SOA) up to DC for resistive loads at 25°C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum drain-to-source blocking voltage for use in 48 V bus systems with margin.
I_D (continuous)	17 A at T_C = 25°C - Sustained current handling with heatsink; derates to 11 A at T_C = 100°C.
R_DS(on)	≤ 45 mΩ at V_GS = 10 V - Low conduction loss enabling <1.3 W dissipation at 17 A.
Q_g	34 nC - Gate charge supporting efficient 500 kHz switching with moderate driver strength.
E_AS	120 mJ - Rated single-pulse avalanche energy for robustness against inductive turn-off transients.
t_rr	55 ns - Fast, soft-recovery body diode reducing switching losses and EMI in synchronous topologies.

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed drain pad for thermal enhancement; 3-pin configuration (G-D-S) with drain connected to tab.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal of N-channel MOSFET	Reference node for gate drive; connects to low-side return path in half-bridge.
Pin 2 (Gate)	Control electrode	Receives voltage-controlled signal; requires 10 V for full enhancement and minimal R_DS(on).
Pin 3 (Drain)	High-side current output node	Connected to PCB copper pour for heat dissipation; ties to input rail or inductive load.

Key Features

Feature	Design Value
OptiMOS™ 3 process technology	Enables lower R_DS(on) × Q_g figure-of-merit for improved efficiency in high-frequency SMPS.
Fully avalanche-rated	Guarantees operation under unclamped inductive switching without failure-no external snubber needed.
Enhanced body diode softness	Reduces voltage overshoot and ringing during commutation, easing EMI filter design.
Lead-free and RoHS-compliant	Meets industrial environmental compliance requirements without exemption waivers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STMicroelectronics STP16NF10	100 V, 16 A, R_DS(on) = 60 mΩ; TO-220 package, no exposed drain pad.	Limited thermal performance in surface-mount designs; unsuitable for high-density layouts requiring D2PAK footprint.	Prefer when through-hole assembly or legacy board reuse is required.
Vishay SIHF17N10C	100 V, 17 A, R_DS(on) = 50 mΩ; TO-220AB package, higher Q_g (42 nC).	Higher switching loss at >200 kHz; less suitable for compact high-frequency DC-DC modules.	Select only if cost sensitivity outweighs efficiency and layout density requirements.

Compared with STP16NF10 and SIHF17N10C, the 64-2143PBF delivers superior thermal resistance (R_θJC = 2.5 K/W vs. ≥3.5 K/W), lower gate charge for faster transitions, and surface-mount compatibility critical for automated manufacturing of power modules.

FAQ

What is the maximum junction temperature for continuous operation?

The 64-2143PBF has a rated maximum junction temperature (T_J) of 175°C. Continuous operation at this limit requires strict thermal design: PCB copper area ≥ 10 cm² under the exposed drain pad, 2 oz copper, and forced airflow ≥ 200 LFM. Derating curves in the datasheet define safe I_D versus T_C up to 100°C case temperature.

Is 64-2143PBF suitable for logic-level gate drive?

No-64-2143PBF is not a logic-level MOSFET. Its R_DS(on) specification requires V_GS = 10 V for full enhancement; at 5 V, R_DS(on) rises to ≥120 mΩ, increasing conduction loss by >160%. A dedicated gate driver (e.g., IR2110 or TC4427) is required for reliable switching.

Does it have integrated ESD protection on the gate?

Yes-the 64-2143PBF includes on-chip gate protection diodes rated for ±2 kV HBM ESD per JESD22-A114. This allows safe manual handling and board assembly without additional external gate Zener clamps, though layout best practices (short gate traces, local 10 Ω series resistor) remain recommended.

Can it replace older 64-2143 without design changes?

Yes-64-2143PBF is the lead-free, RoHS-compliant successor to the legacy 64-2143 (lead-based). Pinout, package dimensions, electrical specs, and thermal characteristics are identical; no PCB or schematic modifications are needed for drop-in replacement in existing designs.
